I have a b18c1 and want to rebuild the head (It was ticking really bad the last time is started it-valve adjustment didnt do ****) I am going to mill the head and use a thin headgasket to bump compression on the stock pistons.

I know that this is not enough compression for skunk 2 stage 2, but i want a cam that will give me more power than stage 1's. Basically i want cams that will give me the most hp for what compression ratio i will be running. Is there a cam that will give me more power than the stage 1's?

Other things i have: dc sports 4-1 header, blox im, skunk exhaust and high flow cat.

I will get the head ported and polished when i pull it off the motor.

PS: i am hopin for 180-190 hp with hondata s200 tuning

your car makes about 144 whp stock so thats a pretty big jump.You are gonna need some pretty extreme cams and a hella good tune. Looked into crowers?

 

You can run Skunk 2 stage 2 cams on the compression you'll be running. You'll prolly be running like 10.4:1 right? That should be fine with stage 2s. I don't see why it wouldn't. Correct me if I'm wrong please.

edit: I've seen GSRs put down 155 to the wheels stock. With intake, IM, cams, higher compression, header, and exhaust, and tuning you'll prolly put down like 185 to the wheels. Prolly closer to 200 with PNP head!

 

iv seen people with built motors go from the stage 1s to the stage 2s and LOSE power. On stock compression i think the stage2's have to much overlap and u lose to much dynamic compression

 

I think its best that you take your car to dyno it from what you have right now...and then after your installation....re-dyno your car at the same place and see what the gains are.....dont pay so much attention to your max hp but see what your gains were...each dyno are different....I think you should stick with stage 1 cams...

 

there are stage1 pros.....but i suggest the stage2 pros.....good hp gains and incredibly noticeable....im actually selling my unused ones if u'd like...but yeah either stage1pros or stage 2 should be fine

 

also if u went w/ the stage2pro's...u'd need to upgrade the internals.... just springs/retainers....and valves if u'd like

 

Are JUNIII like the sknk 2 stg 2? Has anybody ever used the m22xx in their motor?

 

I'm pretty sure that the JUNIIIs are way too extreme for your application.

Look into the Buddy Club 3+ (they don't have 1/2, their 3+ is their stage 1). I remember them making up to like 12 horsepower more than the skunk2 stg.1's in the meat of the power band on omniman's motor, which matters way more than peak power anyway. They aren't a cam that necessitates revving high, either, and you can run them on ITR valve springs/retainers. Sounds like exactly what you're looking for, no?

search for m22's or jun cams....there's been quite a few topic on these cams...or mostly every cam in the market has been discuss...go into the all motor forum...they always discuss cams...

bc3+'s are nice...very good midrange. but dont expect to take them far beyond 8k, they arent a very high revving cam. also, omnimans setup was a b20vtec with lots of other stuff done, so you cant really compare his dyno to relatively stock c1.

 

I think at that time it was a b18 bored over to 1.9? Not quite a b20, probably still enough to make a difference, but I think it illustrates the strengths of the BCs vs. the skunk2s. Hang on, I'll see if I can find it.

 

Thanks to all that posted...I think i am now going to do with the buddy club Spec III's. On a website they said these are good for motors with a cp between 10 and 13. Cheaper than the skunk2 stage 2 also

Sounds good. You don't have the compression for skunk2's anyway, you'd lose power on a stage 2 setup vs. the buddy club's or something similar.

 

what valve train should i also go with. Sould i just go with itr stuff or go all out. IE: Ferrera valves, ferrea springs, ferrea reatiners, new lma's.

Are stock gsr lma's fine for the buddy club spec III's? Im preety shure they should be, i just want to double check before i buy the wrong ones.

 

ITR valvesprings/retainers should be just fine. You don't need to be revving the cams that high since they stop making power only slightly higher than the stock rev limiter, so really stiff springs aren't really necessary.

 

So you think i should be nailing down a good 180-190 whp with:

Stock pistons,
Milled head
bored tb
obx im
greddy header 4-1
high flow cat
buddy club III cams
hondata s200 tuned
probably a apex-i cat back
thin head gasket
port and polish

What compression are you thinking of milling that head to?

I would say to probably expect anywhere from 170-185 with that setup.

 

i have no idead what i would mill it... what would be a safe mill? .02?
